Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to be limiting.

The slide block comprises a roller-type slide block and a ball-type slide block, and the roller-type slide block or the ball-type slide block can be matched with the guide rail to drive the load to do linear motion with high speed and high precision along the guide rail. In order to ensure the precision of linear motion, after the sliders are produced in batches, the assembled sliders need to be detected and classified, and the combination height and the walking precision are mainly detected.

As shown in fig. 1 and fig. 2, the present embodiment provides a detection apparatus for a slider, including a detection platform 1, a guide rail 2, a first detection mechanism 3, and a second detection mechanism 4, where the guide rail 2 is fixed on the detection platform 1, and a slider 100 to be detected is matched with the guide rail 2 and can move along the length direction of the guide rail 2. The first detection mechanism 3 is used for detecting a first reference surface 101 of the to-be-detected slider 100, and the second detection mechanism 4 is used for detecting a second reference surface 102 of the to-be-detected slider 100. The first reference surface 101 is a side surface of the slider 100 to be measured, the second reference surface 102 is an upper surface of the slider 100 to be measured, and the combination height error is determined by detecting the parallel accuracy of the upper surface of the slider 100 to be measured.

In the slider detecting device provided in this embodiment, in the process that the slider 100 to be detected moves along the guide rail 2, the first detecting mechanism 3 detects the parallel accuracy of the side surface of the slider 100 to be detected, and meanwhile, the second detecting mechanism 4 detects the parallel accuracy of the upper surface of the slider 100 to be detected; the combined height and the walking precision of the sliding block 100 to be detected can be detected simultaneously, the detection efficiency is greatly improved, and the method is suitable for batch detection of the sliding blocks.

The first detection mechanism 3 comprises a detection rod 31 and a first dial indicator 32, the detection rod 31 is arranged on one side of a first reference surface 101 of the slide block 100 to be detected and is rotatably connected with the detection platform 1, the detection rod 31 comprises a first end and a second end opposite to the first end, the first end is fixedly connected with a detection head 33, and the detection head 33 is abutted against the first reference surface 101; the first dial indicator 32 is fixed on the detecting platform 1, the first dial indicator 32 includes a first measuring head 321, and the first measuring head 321 abuts against the second end.

The first detection mechanism 3 utilizes the lever principle to directly display the change of the parallelism of the first reference surface 101 through the first dial indicator 32, and the structure is simple. When the sliders 100 to be detected with the same specification are detected, the sliders 100 to be detected only need to be matched with the guide rails 2, the detection heads 33 abut against the first reference surfaces 101 of the sliders 100 to be detected, the first detection mechanisms 3 do not need to be repeatedly disassembled and assembled when batch detection is conducted, and detection efficiency is high.
